.Net 4.6.1 Support

Support for .Net 4.6.1 is now available for Exchange Server 2016 and 2013 with these updates. We fully support customers upgrading servers running 4.5.2 to 4.6.1 without removing Exchange. We recommend that customers apply Exchange Server 2016 Cumulative Update 2 or Exchange Server 2013 Cumulative Update 13 before upgrading .Net FrameWork. Servers should be placed in maintenance mode during the upgrade as you would do when applying a Cumulative Update. Support for .Net 4.6.1 requires the following post release fixes for .Net as well.

Note: .Net 4.6.1 installation replaces the existing 4.5.2 installation. If you attempt to roll back the .Net 4.6.1 update, you will need to install .Net 4.5.2 again.

AutoReseed Support for BitLocker

Beginning with Exchange 2013 CU13 and Exchange 2016 CU2, the Disk Reclaimer function within AutoReseed supports BitLocker. By default, this feature is disabled. For more information on how to enable this functionality, please seeEnabling BitLocker on Exchange Servers.

SHA-2 Support for Self-Signed Certificates

The New-ExchangeCertificate cmdlet has been updated to produce a SHA-2 certificate for all self-signed certificates created by Exchange. Creating a SHA-2 certificate is the default behaviour for the cmdlet. Existing certificates will not automatically be regenerated but newly installed servers will receive SHA-2 certificates by default. Customers may opt to replace existing non-SHA2 certificates generated by previous releases as they see fit.

This will show you how to configure your environment for BitLocker, the disk volume encryption built into Windows 10 Enterprise and Windows 10 Pro, using MDT. BitLocker in Windows 10 has two requirements in regard to an operating system deployment:

A protector, which can either be stored in the Trusted Platform Module (TPM) chip, or stored as a password.

To configure your environment for BitLocker, you will need to do the following:

Configure Active Directory for BitLocker.

Download the various BitLocker scripts and tools.

Configure the rules (CustomSettings.ini) for BitLocker.

Configure Active Directory for BitLocker

To enable BitLocker to store the recovery key and TPM information in Active Directory, you need to create a Group Policy for it in Active Directory. For this section, we are running Windows Server 2012 R2, so you do not need to extend the Schema. You do, however, need to set the appropriate permissions in Active Directory.

Note
Depending on the Active Directory Schema version, you might need to update the Schema before you can store BitLocker information in Active Directory.

In Windows Server 2012 R2 (as well as in Windows Server 2008 R2 and Windows Server 2012), you have access to the BitLocker Drive Encryption Administration Utilities features, which will help you manage BitLocker. When you install the features, the BitLocker Active Directory Recovery Password Viewer is included, and it extends Active Directory Users and Computers with BitLocker Recovery information.

Set permissions in Active Directory for BitLocker

In addition to the Group Policy created previously, you need to configure permissions in Active Directory to be able to store the TPM recovery information. In these steps, we assume you have downloaded the Add-TPMSelfWriteACE.vbs script from Microsoft to C:\Setup\Scripts on DC01.

On DC01, start an elevated PowerShell prompt (run as Administrator).

Configure the permissions by running the following command:

cscript C:\Setup\Scripts\Add-TPMSelfWriteACE.vbs

Add BIOS configuration tools from Dell, HP, and Lenovo

If you want to automate enabling the TPM chip as part of the deployment process, you need to download the vendor tools and add them to your task sequences, either directly or in a script wrapper.

Add tools from Dell

The Dell tools are available via the Dell Client Configuration Toolkit (CCTK). The executable file from Dell is named cctk.exe. Here is a sample command to enable TPM and set a BIOS password using the cctk.exe tool:

cctk.exe --tpm=on --valsetuppwd=Password1234

Add tools from HP

The HP tools are part of HP System Software Manager. The executable file from HP is named BiosConfigUtility.exe. This utility uses a configuration file for the BIOS settings. Here is a sample command to enable TPM and set a BIOS password using the BiosConfigUtility.exe tool:

Add tools from Lenovo

The Lenovo tools are a set of VBScripts available as part of the Lenovo BIOS Setup using Windows Management Instrumentation Deployment Guide. Lenovo also provides a separate download of the scripts. Here is a sample command to enable TPM using the Lenovo tools:

The Microsoft Deployment Toolkit (MDT) 2013 Update 2 (6.3.8330) is now available on the Microsoft Download Center. This update requires the Windows Assessment and Deployment Kit (ADK) for Windows 10, available on the Microsoft Hardware Dev Center. (Note that there are known issues with the v1511 release of the Windows 10 ADK and System Center Configuration Manager; these issues do not directly affect MDT although may still impact ZTI or UDI scenarios.)

MDT 2013 Update 2 is primarily a quality release; there are no new major features. The following is a summary of the significant changes in this update:

Security- and cryptographic-related improvements:

Relaxed permissions on newly created deployment shares (still secure by default, but now also functional by default)

In anticipation of some questions that you may have about this release (or MDT in general):

Q: Should I expect a release of MDT with every new Windows 10 and/or Configuration Manager build release?

No. We shipped multiple MDT releases this year due to the timing of Windows 10 and Configuration Manager releases, but do not intend to keep that same cadence going forward.

Q: What branches of Windows 10 does MDT support?

MDT supports both the current branch of Windows 10 as well as the long-term servicing branch.

Q: What branches of System Center Configuration Manager does MDT support?

For ZTI and UDI scenarios MDT 2013 Update 2 supports the current branch of System Center Configuration Manager (currently version 1511) for an integrated solution for deploying Windows 10 current branch as well as prior Windows versions.

Q: When is the next planned release of MDT?

We do not currently have a timeframe. We will release any tactical changes as needed which may be required to support new builds of Windows 10 or Configuration Manager, but do not currently expect this to be needed.

Q: Is this the last release of MDT?

No, we will continue to iterate and invest in the product.

Q: Why is it still “MDT 2013” when the year is almost 2016?

Two primary reasons. First, we have only made minor changes to MDT which in our opinion does not constitute a major version revision. Second, per the MDT support lifecycle, a new major version will drop support for MDT2012 Update 1 which still supports legacy platforms.
